Study information

Scientific title

A randomised phase II study of paclitaxel with or without GSK1120212 in advanced wild type BRAF melanoma

Acronym

PACMEL

Study hypothesis

This is a randomised multi-centre study. 80 patients (forty in each of 2 arms) with melanoma will be randomly assigned to receive treatment with paclitaxel chemotherapy or the same drug along with GSK1120212, a new medicine. To take part the patient's melanoma must have a normal BRAF gene (at V600), which is about 60% of people with melanoma. This can be checked on a sample of the patient's tumour (usually one that has already been taken as part of their treatment). Prior to the randomised part of the study, between 9 and 18 patients will take part in the trial to establish the best dose of GSK1120212 and paclitaxel in combination.

Condition

Melanoma

Intervention

Dose Escalation Phase: Patients with advanced melanoma will be recruited into 3 dose level cohorts. Three dose levels of GSK1120212, starting at 1.0 mg for the first cohort and escalating by 0.5 mg to 1.5 mg and 2.0 mg for the second and third cohorts respectively. At all dose levels, GSK1120212 will be administered once daily orally in combination with an 80 mg/m2 IV infusion of paclitaxel on Days 1, 8 and 15 of each 4 week cycle. This phase will determine the maximum tolerated dose of GSK1120212 in combination with paclitaxel for the randomisation phase. Paclitaxel will be administered for up to 6 cycles, but GSK1120212 may be continued until disease progression or intolerable toxicity.

Randomisation Phase: Two treatment arms:
1. Maximum 6 cycles of single agent Paclitaxel alone as an 80mg/m2 IV infusion on Days 1, 8 and 15 of each 4 week cycle
2. Maximum 6 cycles of Paclitaxel as an 80mg/m2 IV infusion on Days 1, 8 and 15 of each 4 week cycle in combination with maximum tolerated dose of GSK1120212 once daily orally.
GSK1120212 may be continued until disease progression or intolerable toxicity.

Patients will be followed up every 3 months until disease progression.

13. Patients who are known to be serologically positive for Hepatitis B, Hepatitis C or HIV.
14. Inability to swallow tablets, refractory nausea and vomiting, chronic gastrointestinal diseases (eg, inflammatory bowel disease) or significant bowel resection that would preclude adequate absorption.
